Protect your building and yourself.

Sto Canada offers industry standard warranties for various products and systems, which are project specific and issued by our partner distributors. In addition, Sto is the ONLY EIFS manufacturer that offers a performance warranty that includes workmanship and includes third-party EIFS inspection. The Sto Assured Performance Warranty (APW) provides a building owner a way to ensure the StoTherm ci system installed on their building is the same durable EIFS system that Sto has designed and tested.
